On H∞ Fault Estimator Design for Linear Discrete Time-Varying Systems under Unreliable Communication Link

This paper investigates the fixed-lag fault estimator design for linear discrete time-varying (LDTV) systems with intermittent measurements, which is described by a Bernoulli distributed random variable. Through constructing a novel partially equivalent dynamic system, the fault estimator design is...
